SECT. II. The Remarks concerning Mad, or Distracted Persons.
THE true Account of the Cause of Distraction is this: When the Animal Spirits, by some Accident or other, are so over-heated, that they become unservice∣able* 1.1 to cold and sedate Rea∣soning; and then Reason being thus laid aside, Fancy gets the Ascendent, and Phaeton-like, drives on furiously, and inconsistently. This Combustion of the Spirits hap∣pens, sometimes by over-great Intention of the Mind, in long and constant Study; sometimes by a Fever, which inflaming the Blood, that communicates the Incendium to the Spirits, which take the Original from it: But most usually by the Rage and Violence of some of the Passions, (whether Irascible, or Concupiscible, as they are wont to be distinguish∣ed) a Man setting his Heart vehemently upon some * 1.2 Object or other, the Spirits are set on fire, by the Violence of their own Motion; and in that Rage are not to be governed by Reason. This we have sad Examples of, in Love, in Grief, in Jealousie, in Wrath, and Vexation; and indeed, (saith my Author) Bethlehem is filled with the Instances.
